CHAPTER 37
RADIUS Server Load Balancing
The RADIUS Server Load Balancing feature distributes authentication, authorization, and accounting (AAA)
authentication and accounting transactions across RADIUS servers in a server group. These servers can
share the AAA transaction load and thereby respond faster to incoming requests.
This module describes the RADIUS Server Load Balancing feature.
